The argument should be correct, distinct, unique and practical; The argument must be true and reliable, with sources, full, typical, vivid and concrete;

The argument should be unified in materials and viewpoints, and orderly in logic and reasoning.

Principle:

(1) should be of academic significance, and choose the major issues of this discipline as far as possible, that is, issues that everyone is generally concerned about, thinking about, controversial and urgently needed to be solved.

(2) Find out whether the subject you want to study has been studied before, and it will get twice the result with half the effort to repeat other people's scientific research work. At the same time, for topics that have been studied, you should focus on "new" to have a foothold; It is rare to quote topics that no one or few people have studied, as long as the views are correct and the arguments are conclusive.

③ We should combine our own knowledge structure, promote "long" and avoid "short", and strive to match our major.

Try to choose small topics. The topic is too big, which is often difficult to write deeply, vaguely or time-consuming. Therefore, first determine a general direction and gradually narrow and concretize the scope of the topic.
